i used the professional blades with my feather for around 2-3 yrs as often as 3-4 times per week due to ease and time restraints.
i never had any tugging on new blades and actually miss the level of sharp i had with the feather, i still have 2 of them but they are just not the same feeling as the straights.

I found i used a blade every week - around 5-6 shaves per blade. Seeing responses above, i probably could have stretched a few more out of it. I do travel half the month for work and if i missed the replacement and traveled for a week without replacing - i had to deal with the tugging and irritation as a result.

Perhaps it is the cage - try the professional and maybe just take it slow.
good luck

I just stropped my feather pro and pro guard blades while in my SS on linen then on my leather strop and the blade is very sharp and shaves very smooth. I curious to see how many shaves I can get doing this.
